Heavy-Duty Aluminum Pumps and MotorsPGP 500 Series
This appendix provides overviews of the valvescurrently offered as well as options that are availablefrom the wide range of Parker gear pumps and motors.Many valves are already in production for OEMcustomers on specific pumps or motors, while othershave been supplied for prototype evaluation. A fewvalves are derivatives of valves already in productionand can be produced for OEM customers. Parker’sintegral valve program was developed in response
to requests from our OEM customers to reducethe number and total cost of components on theirmachines. We addressed this challenge by integratingthe valves required for machine functions into ourhydraulic pumps and motors. This integration hasreduced the number of purchased components,eliminated many of the hydraulic hoses and associatedfittings (and potential leak points), and reducedassembly labor costs on the production line.
Comments:The Load-Sense feature allows the gear pump and integralvalve to be used with load-sense directional valves. Thisfeature also allows remote adjustment of the pumppressure up to the limit set by the internal pilot relief.Conversion to the pilot-operated relief valve is achievedby plugging the Load-Sense (LS) port. The pump bodyrequires an outlet port. This pump and valve assemblycan also be used with a small, external, direct-actingrelief valve for remote pressure control of the pump.
Comments:This valve utilizes the same casting, main spool and pilotrelief as the Load-Sense, Pressure-Relief Valve. A small,solenoid-operated, cartridge valve vents the internal pilotflow to the pump inlet to unload the main spool. Theoutlet port is in the pump body and the excess flow (EF)is connected to the reservoir via the heat exchangerand/or the return-line filter.

Variations: PGP 511and PGP 517Specify voltage and whether N/O or NC
Comments:This valve permits pressure unloading of the first sectionin the tandem. The valve may also be remote mounted foruse with tandem or dual pumps. The flow from port P1 istypically combined with the flow from port P2. This valve isoften used on construction machinery, such as backhoeloaders, wheel loaders and cranes. Its purpose is to providehigh flow (from both sections of the tandem) at low ormedium pressures and high pressure with reduced flow(from the rear section only). This allows maximumproductivity of the machine in relation to the poweravailable to the pump.

Comments:The Parker Two-Stage or High-Low Pump is a tandem unit with equal or dissimilar displacements. A two-position/two-wayvalve in the rear cover allows for rear pump unloading. This pump is applied when the prime mover (engine or electricmotor) has limited power. When high pressure is required, the rear section is unloaded to the pump inlet or the tank.When high flow is required at low or medium pressure, the flow of both sections is combined at the outlet port P. In bothcases, the displacements and pressure selected are to be within the power limits of the prime mover.
Note: When the internal vent to the inlet is selected, caution is suggested to prevent extended periods of operation in theunloaded position. The heat generated may lower the fluid viscosity below the minimums required for the pump, whichcould possibly damage it.

Single Pressure-Relief Valve - PGM 505 and PGM 517
Comments:This integral relief valve protects the motor from over-pressurization. It can also be used in series with the main systemrelief valve to limit the pressure differential and output torque of the motor.
Single Pressure-Relief Valve with Anti-Cavitation - PGM 511 and PGM 517
Comments:This integral relief valve protects the motor from over-pressurization. It can also be used in series with the main system reliefvalve to limit the pressure differential and output torque of the motor. The check valve allows the motor and driven load to“spool down” when the fluid supply is shut off or reduced, due to engine speed fluctuations. In series operation, the checkvalve permits the motor to come to a controlled stop, if the outlet flow is suddenly blocked. This check valve reduces the risk ofdamaging the motor or blowing a hydraulic line. Motors fitted with this valve are available with side or rear-facing ports.

Applications: Compressor drives, fan drives, mower bladedrives and water pump drives
Heavy-Duty Aluminum Pumps and MotorsPGP 500 Series
Comments:This valve provides integral, cross-port relief to protect the motor from over-pressurization and to limit torque in bothdirections of rotation. It can also be used in series with other motors downstream, when using an external drain case.By adding or removing shims it is possible to limit change to the factory-set pressure. In order to minimize overalllength of the unit, side ports are standard.

Cross-Port Pressure-Relief Valve with Anti-Cavitation - PGM 511
Comments:Motors fitted with this relief valve may be applied in series or in a hydrostatic transmission. The relief valve provides a limitto the pressure differential and the output torque. The check valves allow flow to return to the inlet of the motor to preventcavitation. It is available with side, rear, or a combination of side and rear ports.
Cross-Port Pressure-Relief Valve with Anti-Cavitation - PGM 511
Comments:This motor has a cross-port relief valve and anti-cavitation check valves in the case drain passages. Motors with thisconfiguration are suitable for open-circuit applications with closed-center valves and hydrostatic transmissions. When themotor and load are limited by the relief valve, the anti-cavitation checks allow internal leakage to be returned to the inletside of the motor. For winches, make-up flow at low pressure is introduced into the case.
Variations: PGM 511Adjustable with shimsWith internal or external drain
Press. Range: Max. setting ............................... 250 bar
Comments:Parker motors are available with brake valves to provide controlled braking of the motor and load. The pressure setting ofthe valve and the stored energy in the load will jointly determine the time to stop the motor. Brake valves must be used withthe appropriate, directional-control valves, which are usually closed-center valves rather than motor spools.
Solenoid Unloading Pressure-Relief Valve for Motors - PGM 511
Comments:A small, solenoid-operated cartridge valve, similar to those used on the PGP511 and PGP517 vents the internal pilot tothe motor outlet to unload the main spool. The outlet port is connected to the tank via the filter and the heat exchanger(if installed). The motor control can be set to provide low-speed operation, rather than coming to a full stop. This allowsfor a quiet fan start from approximately 100 rpm. The solenoid in the valve is available for normally-open or normally-closedoperation. The anti-cavitation check valve allows motor spool-down, when the engine is shut down while the fan is running.
Check Valve and Restrictor - PGM 511
Comments:The Check Valve and Restrictor are used to control pressure spikes between motors in a series circuit. The check valveallows the motor and driven load to “spool-down” when the fluid supply is shut off or reduced due to engine speedfluctuations. In series operation, the check valve permits the motor to come to a controlled stop, if the outlet flow issuddenly blocked. This check valve reduces the risk of damaging the motor or blowing a hydraulic line. The restrictorpermits operation in reverse for cleaning debris or backlapping of the cutters.
